Voice over IP Overview

I recently tried to google for "VoIP basics" and a few similar terms. The results were, uhm, unsatisfactory. The pages in the result set all seem to waste too much of the "real estate" with advertisement, the actual content is short and only touches the surface of individual topics.

The floating point implementation of the codec is available royalty free (see http://www.ilbcfreeware.org/). I cannot offer any direct experience with the codec but I would expect the claims about good quality and packet loss robustness to be true, given the slightly higher bitrate (13.33 or 15.2 kbps).

hello Mr Toncar. I read your article about, "About Jitter".first, thank you for this good and useful article.I try to translate it to persian language.in your article there is: "seach 20 milliseconds". I think your mean was "each" not "seach".

Thank you for the excellent tutorial on SIP and VoIP. I was missing some key points to put it all together. You've done an excellent job in explaining it in simple and concise terms. I will post a link in the PBX in a Flash forums to share with others who use the open source Asterisk distribution. Thanks

Hi, Some good info on various aspects of SIP. As a new beginner it is too much for me but the ground covered is vast. I agree that very few pages related to SIP on Web are useful. Recently I was lucky enough to find some basic Interview Questions on SIP :)
